Researchers use patient’s whole genome to predict his risk for 55 different health conditions
For pathologists, the day draws ever closer when they will use a patient’s whole genome sequence for diagnostic purposes. That’s the implication from research being done at the University of Stanford Medical School where scientists recently made a leap forward in advancing practical application of the human genome to patient care.
Stanford researchers recently announced that, for the first time, a healthy person’s complete DNA was sequenced, then used to create an easy-to-use, cumulative risk report. This study model could catapult patient genomic analysis into clinical laboratories even as it adds personalized medicine to the doctor’s black bag of diagnostic tools within the decade. The Stanford study team reported these findings in a recent issue of Lancet.

Up to 400 times more sensitive than existing ELISA-based methods
Detecting any of seven cancers in their earliest stages may be feasible through the use of a new biomarker chip that was recently unveiled by scientists from Stanford University’s Center for Magnetic Nanotechnology. To give their biomarker chip increased sensitivity over fluorescent detection methods, the scientists use magnetic technologies to accomplish detection.
Reporting in Proceedings of the National Academy of Sciences (PNAS), lead scientist Shan X. Wang, Ph.D., director of the center and professor of materials science and electrical engineering, says the chip is able to detect very low levels of seven cancers. The biodetection chip is to be marketed by Silicon Valley startup MagArray Inc., of Sunnyvale, California. It detects multiple proteins in blood or DNA strands using magnetic technology similar to how a computer reads a hard drive. Developers say this chip could also be used to diagnose cardiovascular disease and monitor cancer therapy.
